226 Chapter 10 and hypothermic patients. However, there were individuals in whom there was a difference of >1 ˚C between short and long TE, see Figure 4. Figure 4: The correlation of brain temperatures calculated based on short versus long TE 1 H-MRS using formula of Wu et al. (A) and the calibrated formula (B). Comparison of rectal temperature and brain temperature Table 2 shows the correlation of the brain temperature, for each method, with rectal temperatures at the NICU. Brain temperatures correlated significantly with temperature before and after MRI when tested in the entire cohort, including both normothermic and hypothermic infants. The rectal temperature before and after MRI were also significantly correlated (r=0.663, p <0.001).
